Adidas Reports Data Breach of a few million customers

Adidas AG ADDYY 2.03% said Thursday that a “few million” customers shopping on its U.S. website may have had their data exposed to an unauthorized party.

Neither the specific number of users affected nor the time frame of the potential breach were immediately disclosed, but the German sportswear maker said it became aware of the issue on Tuesday and has begun a forensic review.

Adidas said they are alerting “certain customers who purchased on adidas.com/US” and that, according to the company’s preliminary examination, data affected include contact information, usernames and encrypted passwords.

“Adidas has no reason to believe that any credit card or fitness information of those consumers was impacted,” the company said.
